Per unit fault impedance

1. The problem statement, all variables and given/known data
Given the relationships:

Xpu = MVAbase / MVAfault

Xpu = ( MVAbase / MVArated ) * ( X% / 100 )

MVAfault = sqrt(3) * V * Ifault

Xohms = [ V / sqrt(3) ] * Ifault

2. Relevant equations

Show that:

Xpu = [ MVAbase / V^2 ] * Xohms

3. The attempt at a solution

No matter how I approach this problem I keep finding that one of the given relationships must be incorrect. Could someone with better algebra skills then me please take a look and confirm whether (a) there is an error in the set problem or (b) I'm just being dense?
